Abstrakt: Deuterium ([SUP2]H) microscopic images with resolution of tens of microns and localized [SUP2]H spectra with volumes in the micro liter range have been obtained on a Varian 400MHz (9.4T) wide bore spectrometer equipped with a 50G/cm gradient system. In order to realize [SUP2]H experiments at 61.4 MHz, a simple RF coil was built. [SUP2]H-Microimaging experiments have been carried out with SE and FLASH pulse sequences and localized [SUP2]H-spectroscopy has been tested on a phantom, which consists of a 2×2×2mm[SUP3] cube with CD[SUB3]OD immersed in D[SUB2]O. Results show that non-invasive investigation of biological samples is possible. As an example for a biological application, the absorption process of D[SUB2]O in a plant fragment (Mikania Cordifolia) has been monitored by acquiring consecutive SE microimages along various hours.
